Abstract: 1,230,248. Doffing and donning. HISPANO SUIZA (SUISSE) S.A. 14 Nov., 1969 [12 Dec., 1968], No. 55897/69. Heading D1D. A doffing and donning device for a spinning machine comprises an endless belt 6 running about pulleys 8 mounted on a movable support 9 running parallel to the spindles. The belt 6 carries gripping devices 10 which have an open slot into which a stud 15, 16 on top of a bobbin engages when device 10 is moved horizontally onto it. Support 9 is mounted to be vertically movable and movable away from and towards the plane of the spindles. Operation. When not in operation the support and therefore belt are moved forwards, down, and back to an unobtrusive rest position. For use it is moved forwards and upwards to position where, when the belt is driven the grippers 10 pass through an empty bobbin loading station 17 where each engages a bobbin fed through a feed spout. When the number of empty bobbins picked up equals the number of spindles, support 9 is moved so that the run of belt 6 which has empty grippers is brought closely adjacent the studs 15 of the full bobbins; a small movement of belt 6 causes the grippers to engage the studs. Support 9 is then lifted to lift the fall bobbins clear of their spindles. The support is then retracted from the spindles and the belt driven so that the grippers with the full bobbins pass through a station 18 where a finger removes the bobbins from their grippers. The empty bobbins are now carried by the run of belt 6 closest to the spindles. Support 9 is then moved to position the empty bobbins over the spindles, is lowered to place the bobbins on the spindles, belt 6 is moved to remove the grippers from the bobbin studs and finally the support 9 is moved to carry belt 6 to its rest position.

Abstract: 1,259,125. Variable-area nozzle. HALLTHERMOTANK INTERNATIONAL Ltd. 8 Dec., 1969 [7 Dec., 1968], No. 58248/68. Heading B2F. [Also in Division F2] A variable area nozzle comprises a plurality of flexible diaphragm devices arranged in sideby-side contiguous relationship and positionable in the line of fluid flow and each diaphragm has an annular series of leaves, which are flexible, to define a central aperture of variable area dependent upon the fluid flow through the nozzle; the pitching of the leaves of each diaphragm device being staggered relative to the pitching of the leaves of the next adjacent diaphragm device, and the flexibility of the leaves of each diaphragm device varying from that of the leaves of the next adjacent diaphragm device to damp any oscillations occuring in the diaphragm devices. The nozzle 5 preferably consists of three flexible diaphragms, 8, 9, 10, which have thicknesses between 1/8-7/16 inch. Each diaphragm has a plurality, preferably ten, of leaves 12, made by providing a number of slits 13 in the material, and which are arranged so that the slits of one diaphragm are intermediate with those of an adjacent diaphragm, the diaphragms defining a central aperture 14. The outer diaphragms have a Shore hardness of 95 compared with the 80 of the central diaphragm to provide the damping mechanism for oscillations in the nozzle. The diaphragms may be made from neoprene, a urethane elstomer 'Polyvon' (Trade Mark) or a flurocarbon. A second embodiment where the diaphragms are inclined upwardly, while being supported on a wire frame, is also disclosed (Fig. 4, not reproduced). The diaphragms are sufficiently stiff to extend freely in the radial direction without drooping when no fluid flow is present, and flexible so that when a fluid flow is present, the leaves 12 fold upwards to increase the area of the throat of nozzle 5.

An article to be labelled pivots an arm 17 about an axis 16 causing a label to unpeel due to the small diameter of the roller 5, a roller 19 then applying the label to the article. After the article passes, the spring 18 restores the arm to the rest position (shown), a rod 13 turning the spool 9 by way of a one-way clutch so as to pick up the label length of the strip. The machine may be pivotally mounted on a member 14 fixed near a conveyer, or may be adapted to be manually held. A pawl 21 pivots to trap the strip against a plate 20 during label application after a label length has been pulled from a supply spool 3. This arrangement enables the machine to be actuated by articles of different heights on the conveyer. If the articles exceed a certain height, the machine pivots on the member 14 against the bias of a spring 15. In a modification, the roller 19 may be a date (or other cipher) stamp, an inking roller being carried by the arm 17. The apparatus may also be used to apply decalcomania transfers, the roller 19 then being kept damp so as to cause the transfer to set on the article.
